[0023] It will be understood that although the terms “first,” “second,” “third,” “fourth,” etc., may be used here to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another.

[0024] Example 1

[0025] Combination Figures 1-2 As shown in the figure, a blood collection needle suitable for infants and young children according to an embodiment of the present invention includes: a puncture assembly 1, which includes a puncture needle 11, a needle holder 12, a needle base 13, and a protective sleeve 14. A needle hole is opened in the center of the needle base 13, the puncture needle 11 is disposed in the needle hole, the protective sleeve 14 is sleeved on one end of the puncture needle 11, and the needle holder 12 is sleeved on the other end of the puncture needle 11; and a fixed transfusion device 2, which includes a transfusion tube 21, a fixing band 22, and a collection needle 23. One end of the transfusion tube 21 is connected to the needle base 13, and the other end of the transfusion tube 21 is connected to the collection needle 23. The fixing band 22 is sleeved on the transfusion tube 21.

[0026] Specifically, this application provides a blood collection needle suitable for infants and young children. When blood needs to be drawn from an infant, the puncture needle 11 is inserted into the blood vessel. After reaching the appropriate working position, the needle core of the puncture needle 11 is withdrawn by holding the needle handle 12, leaving the soft tube of the puncture needle 11 in place for blood collection. This reduces the risk of damage to the infant's blood vessels and minimizes the infant's pain during the blood collection process. Blood flows through the needle hub 13 into the transfusion tube 21 of the fixed transfusion device 2. At this time, the fixing strap 22 on the transfusion tube 21 can be used to fix the child, preventing loosening or displacement and ensuring the smooth progress of the blood collection process. When blood collection is not required, the protective sleeve 14 protects the puncture needle 11 from contamination and reduces the risk of accidental injury to medical personnel, further ensuring the safety of the blood collection process. This effectively solves many problems of existing blood collection needles used in infant blood collection applications, providing a more efficient and safer solution for infant blood collection.

[0027] In some possible implementations, the fixing strap 22 includes a strap body 221, a hook and loop fastener face 222, and a hook and loop fastener face 223. The hook and loop fastener face 222 is disposed on one end of the front side of the strap body 221, and the hook and loop fastener face 223 is disposed on the other end of the back side of the strap body 221.

[0028] Specifically, the Velcro design allows the fixing strap 22 to be adjusted according to the size of the infant's limbs during use, ensuring a tight fit. At the same time, the Velcro is firmly attached, which can effectively prevent the fixing strap 22 from accidentally coming loose during blood collection, ensuring the stability of blood collection.

[0029] In some possible implementations, the puncture needle 11 includes a catheter and a needle core, with the catheter sleeved on the needle core, a protective sleeve 14 sleeved on one end of the catheter, and a needle holder 12 sleeved on the other end of the catheter.

[0030] Specifically, after a successful puncture, the needle core is removed, leaving the soft catheter inside the blood vessel to reduce irritation and damage. The protective sleeve 14 protects the catheter before puncture to prevent contamination, while the needle handle 12 facilitates the gripping and operation by medical staff, improving the accuracy of the puncture, and allows the needle core to be removed after completion.

[0031] In some possible implementations, the collection needle 23 is connected to a blood collection tube, and the protective sleeve 14 is provided with several anti-friction particles.

[0032] Specifically, the collection needle 23 is connected to the blood collection tube and is used to introduce the collected blood into the blood collection tube for subsequent testing. The anti-friction particles on the protective sleeve 14 increase the friction of the protective sleeve 14, making it easier for medical personnel to use.

[0033] In some possible implementations, the fixed transfusion device 2 also includes a flow stop clip 3, which is disposed on the transfusion tube 21 and located between the fixing band 22 and the needle seat 13. The fixed transfusion device 2 also includes a collection sleeve, which is fitted onto the collection needle 23.

[0034] Specifically, the flow-stopping clip 3 can flexibly control the flow of blood in the infusion tube 21. When blood collection is completed or needs to be paused, the flow-stopping clip 3 can be closed to prevent blood backflow or spillage. The collection sleeve is placed on the collection needle 23 and serves to protect it from contamination or damage when the collection needle 23 is not in use.

[0035] In some possible implementations, the infusion tube 21 and the needle holder 12 are both made of PE material, the fixing band 22 is made of rubber material, and the puncture assembly 1 also includes an adhesive band 15, which is adhesively connected to the puncture needle 11.

[0036] Specifically, the transfusion tube 21 is made of PE material, ensuring that the blood is not contaminated during transfusion and is not easily broken under bending or other conditions, while also guaranteeing strength and durability. The fixing strap 22 is made of rubber material, which can fit snugly against the infant's limbs while accommodating slight limb movements, without causing a feeling of restraint. The adhesive tape 15 allows the puncture needle 11 to adhere to the patient's skin surface after insertion, and when the needle core is withdrawn, the fixing of the adhesive tape 15 makes the catheter more secure and less likely to fall off.

[0037] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto.
